MPC8248ZQMIBA

Overview

The MPC8248ZQMIBA is a microprocessor component manufactured by NXP Semiconductors, formerly Freescale Semiconductor. It features a 32-bit architecture with an address bus width of 30 bits and supports DMA channels. The device operates at a maximum clock frequency of 66.7 MHz and utilizes a 64-bit external data bus. It is housed in a BGA package with 516 terminals, measuring 27 mm in length. The unit has 57 I/O lines and functions as a JTAG debugger interface. It complies with the S-PBGA-B516 form code and is rated for operation up to 70 °C.

Feature Summary

• Supports JTAG debugging functionality
• Integrates Direct Memory Access (DMA) channels
• Features a 32-bit core architecture

Applications

• JTAG Debuggers

Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists NXP Semiconductors as the producer despite the historical Freescale association. Confirm the specific suffix ZQMIBA corresponds to the required BGA-516 package and 66.7 MHz speed grade. Ensure compliance requirements are met, as the component is noted as non-RoHS compliant in available records. Validate the operating temperature range against system thermal constraints before procurement.

Selection Notes

Select this component when a 32-bit embedded processor with integrated JTAG debugging capabilities is required. The 66.7 MHz clock speed suits applications not demanding high-frequency processing. The 516-pin BGA package necessitates PCB designs supporting fine-pitch surface mount technology. Consider the 64-bit external data bus width for memory interface compatibility. Verify that the 70 °C maximum operating temperature aligns with the intended environmental conditions.

Part Context

This part belongs to the PowerQUICC family of embedded processors developed by Freescale Semiconductor, now NXP. These processors are designed for communications and networking applications, integrating cores with communication processor modules. The MPC8248 series specifically targets high-performance embedded control tasks requiring reliable debugging interfaces and established 32-bit processing architectures.
